T0 all whom it may concern:

Be it known that I, JOHN CI-IAMBERLIN, a citizen of the United States,residing at Flat Rock, in the county of Wayne, State of Michigan, haveinvented certain new and useful Improvements in Tongue- Truck TurningAttachments for Binding-Machines; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon, which form a part of thisspecification.

This invention relates to a tongue truck turning attachment especiallydesigned and adapted for use in connection with binding machines and thelike, and consists inthe novel construction and arrangement of parts ashereinafter fully set forth and pointed out particularly in the claims.

The main object of the invention is the provision of simple andefiicient means for employment in connection with the ordinary types ofgrain binding machines as now in common use, to facilitate the turningof the machine at the corners of the grain so as to present the cutterbar to the standing grain in the required position to enable the cuttingof a full swath at any desired angle to the preceding cut withoutnecessitating the backing of the machine or maneuvering with the team toattain such position.

The invention pro-vides for such a construction and arrangement of partsattachable to the tractive tongue, the tongue truck and the guidingtongue of the machine as will control and accelerate the turningmovement of the tongue truck through the swinging movement of theguiding tongue, in such manner as to enable the machine to be readilyturned and placed in the desired position through the mere turning ofthe team or tractor in the required direction, and which may be effectedwithout danger of fouling the team with the reel of the machine as isfrequently the case in making such turns with machines as nowconstructed.

rThe above objects are attained by the employment of the constructionand arrangement of parts, the preferred embodiment o-f which isillustrated in the accompanying drawings, in which,

Figure 1 is a diagrammatic plan view of a portion of a binding machine,showing the tongue truck as equipped with my improved turningattachment, and indicating by dotted lines the action of the device inturning the tongue truck by the movement of the team to eect the turningof the machine. Fig. 2 is a plan view of a portion of a. binding machineshowing the tongue truck and turning attachment thereon in the operatedposition for effecting the turning of the machine. Fig. 3 is a centralvertical fragmentary section through the tractive tongue, the tonguetruck and the guiding tongue. Fig. 4 1s a transverse fragmentarysectional view through the parts on line 4 4 of Fig. 3. Fig. 5 is a sideelevation of a portion of a binding machine showing the tongue truckequipped with the improved turning attachment, in which one of thetongue truck wheels is omitted to better show the attachment of theparts. Fig. 6 is a fragmentary perspective view of the tongue truckturning attachment as applied to the tractive tongue, tongue truck andguiding tongue of the machine, the parts being in their normal position.Fig. 7 is a perspective view of a yoked fitting for pivotally connectingthe tongue truck with the guiding tongue.

Referring to the drawings by the characters of reference marked thereon,1 represents the plat form frame, 2 the cutter bar, 3 the grain wheeland 4 the main driving wheel of an ordinary binding machine, to theframe 1 of which the usual stub or tractive tongue 5 is pivotallyattached at 6.

The usual tongue truck, comprising fianged wheels 7 journaled upon'theends of an axle 8, which is pivotally connected to a vertical stem 9, ismounted to support the outer end of the tractive tongue 5 by means of aforked fitting 10 secured to the end of said tongue, and which receivesand forms a vertical journal bearing for the upper end of the stem 9.Secured rigidly to the stem 9 and lying within the forked fitting 10 isa forked fitting 11 to which the guiding tongue 12 is ordinarilypivotally attached to swing vertically thereon and to impart ahorizontal swinging movement to the tongue truck, but in the presentinstance a yoked fitting 18 is interposed between the end of the guidingtongue 12 and the fitting 11 and is provided with ears 14 to whichfitting it is attached by means of a pin or bolt l5 passing therethroughand through the fork of said fitting 11. The end of the tongue 12 ispivotally attached to the fitting 13 to swing horizontally thereon bymeans of a pin or bolt 16 and is embraced by the odset yoke 17 of saidfitting which normally engages with said tongue upon one side tomaintain it in alinement with the tractive tongue 5, and is adapted toengage and limit the movement of said tongue at its opposite side at anangle of approximately 4:5 degrees to the planeof the tractive tongue(See Figs. 2, 3 and 4).

The Whittle-trees 18 to which the horses for drawing the binding machineare attached are carried upon the upper end of the stem 9 of the tonguetruck, or may be mounted in any suitable manner upon the end of thetractive tongue 5. All of the features thus far recited with theexception of the yoke fitting 13 are commonly employed in theconstruction of binding machines and form no part of the presentinvention.

rlrhe novel features of the invention comprise the following describedattachments by means of which the turning of the tongue truck isaccelerated and controlled by the movement of the tongue and the turningof the machine is facilitated. The axle 3 of the tongue truck isprovided with an angu` lar arm 19 which may be rigidlysecured to saidaxle in any suitable manner, but in the present instance is securedthereto by means of a clamp Vplate 20 through which and the the end ofsaid arm bolts 21 are passed and receive nuts 22 by which the parts aredrawn firmly together upon said axle. Said arm 19 extends rearwardly andoutwardly from said axle and terminates in an up wardly extending endportion 23. (See Figs. 2, 5 and 6). Extending laterally from thetractive tongue 5 are brace arms 24: which are secured at their innerends upon opposite sides of the tongueV 5 by bolts 25 or other suitablemeans, and at their outer ends are connected together and to one end ofa brace rod 26by means of a bolt or Cotter pin 27. r1`he opposite end ofthe brace rod 26 is bolted or otherwise suitably secured to the tractivetongue Secured to the guiding tongue 12 at a point in advance of itspivotal connection with the tongue truck is a pulley 28 carried in ablock 29 which is pivotally attached to said tongue by means of a boltor staple 30. Rove about said pulley is a none-elastic flexiblemember31, preferably a cable or chain,` one end of which is suitablyattached to the pin 27 of the brace arms 24:, and the opposite end ofsaid chain is suitably secured at 32 to the upturned end 23 of the arm19 ofV the tongue truck. The length of the chain 31 is such as tonormally retain the guiding tongue in alinement with the tra'ctivetongue and te position the axle of the tongue truck at right-anglesthereto. 1n this position the guiding tongue, lying incontact with oneside of the yoke 17 of the fitting 13, steadies the tongue truck againsta swinging movement in one direction toward the guiding tongue, while aswinging movement of the tongue truck in theopposite direction isretarded by means of a spring tensicned steady rod 33, one end of whichpasses freely through an aperture 34 in the end 23 of the arm 19 and isprovided at its opposite end with an eye 35 for the reception of a bolt3G, by means of which it is pivotally attached to the guiding tongue 12at a point in advance of the pivotal connection of said tongue with thetongue truck. A compression coil spring 37 cmbracing said rod isinterposed between the end 23 of the arm 19 and a collar 33 adjustablysecured to said rod by means of a set screw 39. (See Figs. 5 and 6.) Itwill be observed that by this arrangement the tension of the spring 37will be exerted through the rod 33 upon the tongue 12, and upon thetongue truck at one side of its pivotal axis through its engagement withthe arm 19 of the axle of said truck, whereby the tongue will beyieldably held in contact with one side of the yoke 17 to prevent aforward swinging movement of the truck wheel upon the corresponding sideof the truck. rlhe truck wheel upon the opposite side will be likewiseyieldably retarded against a forward suf'inging movement in a manner toobviate any undue wabbling movement of the truck that might beoccasioned by a variation in the resistance against the wheels intraveling forward, while the sliding movement of the steady rod throughthe truck arm 19 against the tension of the spring 37 permits said truckto swing at a greater ratio of movement than the movement of the guidingtongue 12 as motion is imparted thereto through the chain drivingconnection, as clearly illustrated in Fig. 2.

The steps in the operation of the device in turning the machine are bestillustrated in the diagrammatic view of Fig. 1, in which the machine isshown in position to be turned so as to present the cutter bar to thegrain (as indicated at 10) at right-angles to the preceding eut, incompleting which out the cutter bar of the machine is stopped slightlyin advance of the standing grain. The team indicated at L11 is thenswung to the left, to the position indicated by dotted lines 412. 1nmaking this movement the guiding tongue 12 in swinging about the axis ofthe tongue truck draws bodily upon the chain 31, which, being anchoredat one end to the brace arm 24 of the tractive tongue, is caused to payout upon that side in passing through the pulley block 29 of the guidingtongue 12, and to take up on the side attached to the arm 19 of thetongue truck, thus drawing upon said arm and tongue and imparting anaccelerated swinging movement to the tongue truck with relation to themovement of the guiding lll) tongue, which augmented movement ispermitted by the sliding of the steady rod 33 through the arm 19 againstthe spring 37 and the pivotal connection of said tongue with the tonguetruck. The relative arrangement of the parts is such that when thetongue shall have reached a position approximately at an angle of 45degrees to the tractive tongue the axle of the tongue truck will haveswung degrees, or to a position in alinement with said tractive tongue,as shown in Figs. l and 2. In this position the wheels of the tonguetruck are so set as to travel in the arc of a circle of which the mainwheel 4 of the machine forms the axis, and by the further forwardangular movement of the team to the position indicated at 43 the machinewill swing upon the pivot formed by the main wheel 4 so as to carry thegrain wheel 3 in the arc of a circle about said main wheel and presentthe cutter bar 2 at an angle of approximately 45 degrees to theA line ofthe standing grain40. The angle of the tongue truck in this position ofthe machine will have swung out of alinement with the tractive tongue toa position so as to travel in the arc of a circle with the main wheel 4,and through the further forward angular movement of the team toward thegrain the machine will be swung upon a pivot formed by the grain wheeland the cutter bar of the machine will be presented to the grain, asindicated by the dotted position 44, in position to cut a full swath atright-angles to the preceding cut when the tongue truck will haveassumed its normal position as indicated by dotted lines at 45. In thisposition the tongue truck is steadied against a wabbling movement by theengagement of the yoke with the guiding tongue upon one side and thetension of the coil spring of the steady rod engaging the tongue and armof the truck upon the opposite side.

t will be apparent that by the employment of the foregoing constructionand arrangement of parts in connection with binding machines, that theturning of the machine at the corners of the standing grain may bereadily effected by the simple operation of turning the team or tractorin a forward angular direction at the completion of each cut, and thatthe loss of time incident to the necessity for backing up andmaneuvering with the team to effect the turning of the machine as iscommon is avoided, thereby saving materially in the waste of' energy andtime in harvesting the grain.

It should be understood that the application of this device is notlimited to the particular type of tongue truck illustrated herein, butmay be applied with equal efficiency to various types of machines as nowin common use, in which it may require some variation in the size, shapeand manner of attachment of the parts but which will not involve amaterial departure in the general plan, arrangement and cooperativerelations of the essential elements disclosed herein and comprised inthe appended claims.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is:
